*Shipping weights include base unit plus packaging.

System Design Manual, Part 3.

†If components are to be split, additional refrigerant will be needed.

 

**Two-speed motor.

 

††Use Type L copper only.

 

NOTE: Fasten threaded rods through holes in end frames. Use 2 rods on each side of unit for a total of 4.
